The keyboard contains five regions, organized by the direction of the root first stroke. Each region contains five keys (making twenty-five keys in total), and each key contains a number of character roots.

Each region proceeds in the same manner, from the inner-most key on the keyboard to the outer-most. Region 1 (lateral) is represented by keys 11-15, region 2 (vertical) by keys 21-25, region 3 (left sweep) by keys 31-35, region 4 (dot/right sweep) by keys 41-45, and region 5 (bend) by keys 51-55.

We will refer to the individual keys by the key number and letter: neither 12 nor F, but 12F. Thinking of the keys in this notation will help your conceptual understanding of WuBiKanJi . However, we will refer to the WuBiKanJi codes, composed of multiple keys, by only the letters: QWERT, for example.

And in Japanese language there have another keyboard of Kana keyboard so there have Japanese character in this keyboard diagram(たていすか).
